I'm neither a birdwatcher nor gardner, I'm just an aminal lover. I work outside across from the Sears/Willis Tower in Chicago where theres the 311 Buidling Park (Jackson side).
Chicago has a extremely large pigeon population. In the 311 park you'll find a mix of both pigeons and house sparrows. I'm actually a "sparrows person" but I love and feed the pigeons also.
In the past year I've befreinded a number of these birds. There's one non-breeding male LBJ, "little brown job", with one leg. He waits for me every morning until I arrive to the Sears Tower. He comes up to me on the sidewalk, looks up at me and melts my heart as I dig into salflower hearts, bread and popcorn. He sits there patiently until I feed him. I know house sparrows are social and aggresive birds but I don't care about what they say that sparrows as being mean. I feed him and his flock every day at Sears Tower and I feel I've done a great deed.
I feed the pigeons also and there's one particular pigeon, "Ozzy", that actually rests upon my kiosk asking to be fed. This is great fun and attracts many future customters....
